circuit idea to connect multiple POSISTORr in series.
When One POSISTORr detects overheat at least, a
comparator can work by the sharp temperatureresistance characteristic. It easily allows changing a
number of POSISTORr or sensing temperature in the
same basic circuit design.

1. High accuracy and highly sensitive temperature
sensing is mode possible by the small size and high
accuracy NTC Thermistor.
2. Narrow space temperature sensing is made
possible by the small sensing head and the thin
lead wire.
3. Flexibility and a wide variety of lengths (25mm to
150mm) enables the design of flexible temperature
sensing architectures.
4. This product is compatible with our 0402 (EIA) size
chip Thermistor.
5. Excellent long-term aging stability.
6. This is halogen free product.
* Cl=max. 900ppm, Br=max. 900ppm and
